Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx 8'g/WZY~~  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm ]*zF#Voc  
Type: Double Bounces O@E&lP6  
The '****' denotes a possible internal focus >|z=-hqPK  
RMS is the RMS spot radius on axis at the primary wavelength. to:hMd1T  
RMS values of 0.00 indicate that an accurate RMS ZMx_J  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is [ddEt  
non-rotationally symmetric or uses non-standard surfaces.
